The answer to 1 foot 11 inches plus 7 feet 10 inches (1' 11" + 7' 10") is displayed below:
9 feet 9 inches
Here is how we calculated 1 foot 11 inches plus 7 feet 10 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
1 foot 11 inches = 23 inches
7 feet 10 inches = 94 inches
Then, we added the inches together to get the total number of inches:
23 + 94 = 117 inches.
Finally, we converted 117 inches into feet and inches to get the answer.
1' 11" + 7' 10" = 9' 9"
Note: There are 12 inches in a foot. Thus, you multiply feet by 12 to get only inches, and
to make it back to feet and inches we divided total number of inches by 12.
